To all whom it may concern: 7

Be it known that I, THOMAS WV. Goornn,

a citizen of the United States, residing at Buckhead, in the county of Morgan and State ofGeorgia, have invented certain new and useful Improvements in Steam Heating Systems; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it assembled position therein.

appertains to make and use the same.

This invention relatesbroadly to locomotive boilers, and has particularreference to that type of systems employed in connection with locomotives for heating the feedwater prior to its entrance into the boiler.

As its principal object, this invention contemplates the provision of means for utilizing a portion of the exhaust from the steam chest of the locomotive for partially heating the feed water for the locomotive, be-

locomotlve and preferably at the lower part fore it enters the boiler.

A further object is to simplify the construction of devices of this general character to such an extent that they may be cheaply manufactured, and. durable and efficient in their operation.

A still further object is to construct this invention with such regard as to proportion, number and arrangement of parts that it may be readily and conveniently applied to any locomotive of standard-type without necessitating the alteration or disassembling of any of the partsof the locomotive.=

A further object. is to provide means for drawing the feed water into the lead pipes to the boiler at that point of the water tank which is of the highest temperature.

A yet further object is to provide means for utilizing the water condensation, of the exhaust steam employed in heating the feedwater, by reconducting' itto the boiler after it has accomplished theheating of the feed water.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims which.

are appended hereto and form a' part of this application.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts: Figure 1 is a side elevation with several of the side plates broken away tomore clearly disclose the assembled relation of the various parts of this invention. Fig. 2 is a top plan View of the locomotive. Fig. 3 is a side elevation of the tender with a portion of the side broken away to clearly illustrate the arrangement of the heater; and Fig. 4 is atop plan view of the tender wit-h the invention in This invention consists essentially in two main elements, the pipes for conducting the exhaust steam from the steam chest, to the tender water tan-k and for reconducting the heated feed water back to the boiler, and

the heater employed in utilizing the exhaust steam for heating the feed water. Taking up theseelements in the order name-d, there has been provided a pair of cylindrical casings 1 and 2 arranged on each side of the thereof. Lea-ding into each of the casings from the exhaust pipe of the steam chests B and 4 are apair of steam pipes 5 and 6.

The pipe'6 is directed through the casing 2 "to its far end, and is-then returned tothe forward end as illustrated in Fig. 1, and

directed to the exhaust stack, as at 7 in Fig.

1. The pipe 0 is arranged withinthe casmg 1 1n a slmil ar mannerhavmg its lower terminal in communication with the exhaust stack as at 8-in- Fig. 2. The pipe 5, however,-

is' tapped as at 9 by a pipe 10 which leadslrearwardly intothe water tank 11 of the- 1 tender, as illustrated in Fig. 3,. andis adapted to conduct a portion of the exhaust 1 l steam through a heating coil 12 arranged in a preferably cylindrical closed casing 13, iwhich may be mounted in the tank 11 of the tender in any desired manner.

Com-

municant with the casing 13 and at the upper portion thereof, as at 1 1, is a water pipe 15, provided to conduct the water forced into the casing, in a manner to be hereinafter described, into the boiler 1.6 of the loco-motive. This pipe 15 is passed .through the entire length of the casing 1,

is then directed, as at 17, through thefire' :tubesof the locomotive, thence through the fire box, as at 18, and subsequently through the casing 2, as at 19, from which it leads into the boiler 16, as indicated at 20. A force pump 21 is arranged within the tender tank 11 and is designed to force the water from the tank into the casing 13, and at the stack, as at 8. As above described, a

lower portion thereof. pump 22 is mounted in the engine cab and is attached to the pipe 15 to force the water into the locomotive boiler 16.

The actual construction being thus disclosed, it now remains to describe the operation and to enumerate the many advantages resulting from the novel form of structure of this device.

Briefly, the operation is as follows: The steam exhaust from the cylinder 4 is conducted by the pipe 5 through the casing 1 and thence to the atmosphere through the portion of the steam is shunted through the pipe 10, and passed through the water tank 11 into the casing 13 and then finds its way through the coil heating pipe 12 to the top of the casing 13 as at 23, where it impinges against the casing and condenses, mingling with the water forced from the tank 11 into the casing 13 by the pump 21. The pump 22 acts to draw the water thus heated within the casing through the pipe 15, which, being communicant with the upper portion of the casing 13 draws off the hottest water in the casing. It will be apparent from the above disclosures that the feed water conducted through the pipe 15 is subjected to four super-heating elements, being first passed through the steam heating cylinder 1, thence through the fire tubes of the locomotive, subsequently through the fire box and finally through the steam heated cylinder 2 from which it issues into the locomotive boiler 16.

In this manner, the temperature of the feed water is raised to the highest possible degree of heat obtainable by employing the exhaust steam as a heating means.

It is desirable to emphasize the fact that inasmuch as this invention consists so far as an apparatus employed is concerned, in mechanical structures which are in themselves neither new nor novel, it rather makes claim to display of invention because of the novel and eflicient arrangement of the various mechanical means employed.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction,

A similar force proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claims.

What is claimed is:

1. The combination with a boiler, smoke stack, fire box and feed tank of a locomotive steam engine, of a coil radiator mounted in the feed tank, a sealed casing for said radiator, a force pump mounted within said feed tank and connected with the lower terminal of said sealed tank, a cylindrical casing arranged on each side of said locomotive, a steam pipe of each cylindrical casing connected at one terminal with the exhaust pipe of the steam chest and at its other terminal with the smoke stack, said pipe coiled within said cylindrical casings, a second steam pipe connected with one of said first steam pipes within one of said cylindrical casings at one terminal and at its other terminal to the lower coil of said coil radiator, a water pipe connected at one terminal. with the upper portion of said sealed casing and at its other terminal with said boiler, said water pipe directed through one of said cylindrical casings, the fire tubes of said 10- comotive, the fire box and finally through the other of said cylindrical casings and into said boiler and a force pump adapted to force the water from said feed tank through said water pipe.

2. The combination with a boiler, smoke stack, fire box and feed tank of a locomotive steam engine, of heating means mounted within said feed tank, cylindrical casings secured to said boiler, pipes connected with the steam chest of the locomotive, coiled within each of said cylindrical casings and terminating in upwardly extending portions communicant with the smoke stack, a pipe connected with one of said steam pipes and with said heating means, aheated water supply pipe connected with said heating means and said boiler, said last named pipe directed through one of said cylindrical casings, the fire tubes, the fire box, into the other of said casings and finally into said boiler, and a plurality of pumps for circulating the water in said pipes.

In testimony whereof I aflix my signature in presence of two witnesses.

THOMAS W. COOPER.
